The Holocene calendar, also known as the Holocene Era or Human Era (HE), is a year numbering system that adds exactly 10,000 years to the currently dominant AD(or CE) numbering scheme, placing its first year near the beginning of the Holocene geological epoch and the Neolithic Revolution, when humans transitioned from a hunter-gatherer lifestyle to agriculture and fixed settlements. The current year in the Holocene calendar is 12,017 HE.

The Republic of China calendar (traditional Chinese: 民國紀元; simplified Chinese: 民国纪元; pinyin: Mínguó Jìyuán; Wade–Giles: Min2-kuo2 Chi4-yüan2) is the method of numbering years currently used in Taiwan by officials and other territories under the control of the Republic of China. It was used in mainland China from 1912 until the founding of the People’s Republic of China in 1949.

Following the Chinese imperial tradition of using the sovereign’s era name and year of reign, official ROC documents use theRepublic (traditional Chinese: 民國; simplified Chinese: 民国; pinyin: Mínguó; literally: “People’s State”) system of numberingyears in which the first year was 1912, the year of the founding of the Republic of China. For example, 2017 is the 106th “year ofthe Republic”.
